정보문화의 전개에 따라 사회적 정보문제와 개인적 정보문제의 질적, 양적인 분화과정에서 발생하는 정보의 패러독스, 정보기술의 패러독스, 기회의 패러독스, 정보의 참조문제, 정보의 타당성 문제를 분석하고, 분화과정에서 나타나는 모순을 통합적으로 조정할 수 있는 조정매체로서의 정보교육과 정보자주성 문제를 다루었다.

TV animation has come a long way to this date since popular animation programs were aired on TV, such as 'Run Little Tiger', 'Run Honey', 'Hurry-Scurry Yeongsimi', beginning with 'Wandering Magpie' on KBS in 1978. However, problematic production process has resulted in the degradation of quality. Consequently, the dwindling viewing rate forced animation advertisers to leave, and the animation production shrank. Under those unfavorable circumstances, the government started to heed messages transmitted from animation producers and went ahead with the 'animation broadcasting quota' in a bid to help revitalize Korean animation industry. This study aimed to identify problems and set the direction for the animation industry by analyzing its fundamental and structural problems.

Hong and Yeo choose the intention criterion instead of the realization criterion for distinguishing deductive and inductive argument in their paper. This study aims to criticize their argument. I contend that their argument confuses argument reconstruction and argument classification[evaluation], and is making the mistake of utilizing the realization criterion when attempting to make up for the difficulties of the intention criterion. Also, most logicians, including Hong and Yeo, support the division of the argument into deductions, inductions, and bad arguments. Here I insist on a binary division of only deduction and induction. Finally, I argue that there is no need to teach the distinction between deduction and induction when teaching logic.

In fuzzy logic control, static fuzzy rules cannot cope with significant changes of parameters of plants or environment. To solve this prohlem, self-organizing fuzzy control. neural-network-hased fuzzy logic control and so on have heen introduced so far. However, dynamically changed fuzzy rules of these schemes may make a fuzzy logic controller Fall into dangerous situations because the changed fuzzy rules may he incomplete or inconsistent. This paper proposes a new adaptive filzzy logic control scheme using a predictivc neural network. Although some parameters of a controlled plant or environment are changed, proposed fuzzy logic controller changes its decision outputs adaptively and robustly using unchanged initial fuzzy rules and the predictive errors generated hy the predictive neural network by on-line learning. Experimental results with a D<' servo-motor position control problem show that propnsed cnntrol scheme is very useful in the viewpoint of adaptability.

Objectives: The primary objective was to test the phenomenon known as the insight paradox, which refers to the association between higher levels of insight and lower self-esteem, higher hopelessness, and a higher perception of social prejudice among patients with schizophrenia. Methods: A total of 216 outpatients with schizophrenia according to the DSM-IV diagnostic criteria were recruited. All participants were receiving ongoing outpatient treatment and were in a stable phase of the disorder. The participants were divided into a good-insight (N=109) and a poor-insight (N=107) group by the direct interview and the mean score of questionnaire. The parameters used for analysis and comparison were demographic variables (age, gender, education), clinical variables (age at onset, number of hospitalizations), self-esteem, hopelessness, self-stigma, and quality of life. Results: Compared with the poor-insight group, the good-insight group was found to have a lower number of hospitalizations, lower self-esteem, higher hopelessness, lower quality of life, and a higher level of internalized stigma. Conclusion: The insight can cause the negative consequences in patients with schizophrenia. Therefore, clinicians should pay attention to the negative aspects of insight for improving the quality of life in the treatment of patients with schizophrenia.

Shock wave model describes the propagation speed of kinematic waves in traffic flow. It was first presented by Lighthill and Whitham and has been deployed to solve many traffic problems. A recent paper pointed out that there are some traffic situations in which shock waves are not observable in the field, whereas the model predicts the existence of waves. The paper attempted to identify how such a counterintuitive conclusion results from the L-W model, and resolved the problem by deriving a new asymptotical shock wave model. Although the asymptotical model successfully eliminated the paradox of the L-W model, the validation of the new model is confined within the realm of the deceleration flow situation since the model was derived under such constraint. The purpose of this paper is to derive the remaining counter asymptotical shock wave model for acceleration traffic flow. For this, the vehicle trajectories in a time-space diagram modified to accommodate the continuously increased speed at every instant in such a way that the relationship between the spacing from the preceding vehicle and the speed of the following vehicle strictly follows Greenshield's model. To verify the validity of the suggested model, it was initially implemented to a constant flow where no shock wave exists, and the results showed that there exists no imaginary shock wave in a homogeneous flow. Numerical applications of the new model showed that the shock wave speeds of the asymptotical model for the acceleration flow tend to lean far toward the forward direction consistently. This means that the asymptotical models performs in a systematically different way for acceleration and for declaration flows. Since the output difference among the models is so distinct and systematic, further study on identifying which model is more applicable to an empirical site is recommended.

Purpose: This study was conducted to study the attitude of Korean lawyers toward withdrawal of life sustaining treatment, and compare and analyze different types of their attitudes. Methods: Research design of this project was Q methodology approach. The study population was 24 lawyers, aged from 32 to 69 years. Q sample to investigate the attitude of the lawyers toward withdrawal of life sustaining treatment included 34 statements obtained from literatures, TV debate, and depth interviews of 5 lawyers among the lawyers included. After listening to the purpose and method of the study, the 24 lawyers agreed to fill out a survey asking sociodemographic information, and the information was distributed in 9 scale Q-sample. Results: The collected data were processed through QUANL PC program and sorted into 5 types as follows: The first type was 'Choosing to withdraw life sustaining treatment', the second 'Withholding life sustaining treatment' regardless of the cost, the third is neutral type that claims that humans have the right to decide the death and life, and demands the proper legalization to protect such rights, the fourth type agrees to withdrawal of life sustaining treatment, nevertheless, admits that one has a rigt to withhold one's own life treatment, categorized as self contradiction type. The fifth type believed that 'Life and death are providential' with the faith, therefore, such authority to decide life and death belongs to God, but not human beings. Conclusion: In conclusion, the lawyer's attitudes toward withdrawal of life sustaining treatment were grouped into five different types as follows: 'Choosing to withdraw life sustaining treatment', 'Withholding life sustaining treatment', 'Demanding legalization', 'Self contradiction type', and 'Life and death are providential'.
